We're using radiusd-freeradius package. Our access servers are happy.
Included sql support fits our needs with several thousands of users.
it's fast (with fast hardware of course!). Features expanded.
We do not encounter old cistron-radius problems anymore
-in the same pc/os system- like uncertain daemon closures.
Info can find on www.freeradius.org .

The only commercial product I use at work that I am actually happy
with is my radius software. I use Radiator, and I love it. I have
the Enterprise Pack which gives me unlimited upgrades (as in
"forever") as well as a couple other packages they sell (also with
unlimited upgrades). The server is written in Perl and easily
extendable. I'm a Perl nut, so that is a huge plus for me. The
company's website is http://www.open.com.au/. Have a look and see if
you like it.

Fully agree (same here). Radiator is the only commercial software I
really can recommend. It's quite cheap and you can by a lifetime
company wide license including all upgrades etc. And don't forget,
it's Perl, so its extensible, you can use whatever Perl module (LDAP,
DBI (MySQL, PostgreSQL, Oracle,...), other Radius servers,...) as
backend. And if you find a bug (or missing feature), you can fix it
yourself, because you get the source (this isn't usual on commercial
software).
Tschoeeee
